Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
Designing the concrete mix The first and most important step in the process is to determine the ingredients that will make up the concrete and their proportions. As should be apparent from the previous section, there are many variables to consider including cement type, aggregate size and type, amount of water, and mineral and chemical admixtures.
Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.
